Tropical rainforests are located along the equator and are filled with millions of plants and animals. Scientists estimate that the rainforests maintain more types of animals and plants than all the other biomes combined. Because of the location near the equator, the temperature is consistent, between 70-90 degrees - with lots of rain - year round.The forest has three layers,: the ground story, the understory, and the canopy. The ground story is covered with foliage, roots and ground dwelling animals. The understory has small plants, trees, and many animals. The canopy offers large treetops, birds and other flying animals. Rainforests are home to many types of birds, mammals, reptiles, insects, flowers, hardwood trees, and medicinal plants.
